In the midsummer of 1914, Guseva traveled with Rasputin to his hometown of Pokrovskoye in Siberia. Upon meeting him outside the church in the town, Guseva charged at him and sliced open his stomach. Rasputin's intestines fell out, and he clutched at them. He then smiled at Guseva, and used the shard of the Imperial Sceptre that he had worn around his neck to force her to mutilate herself. Guseva's face became heavily deformed as a result, most notably with the loss of her nose.
Guseva was subsequently imprisoned in the asylum at Krasnoyarsk until she was freed from her cell by the Assassin Nikolai Orelov on 15 November 1917. In exchange for telling him what had occurred during her assassination attempt, she would get her freedom. Once she fulfilled her end of the deal, Guseva asked the Assassin to put her out of her misery, and so Orelov thrust his Hidden Blade through her heart, killing her.
